in the previous article, we discussed the Web site optimization principles for MSN, and now let's take a look at what to do with Yahoo to ensure a better ranking.
Despite such rumors, Yahoo! is still the second-largest search engine, and no web site can ignore its influence. The Yahoo! Search ranking algorithm is based on its Inktomi technology, which was purchased in 2002, before Yahoo! used the engine of its current biggest competitor, Google. Because of this, the difference in the algorithm results in a lot of Google and MSN ranked very good site in the Yahoo! rankings, and vice versa, then, Yahoo's algorithm is there any special place?
Strictly speaking, for Yahoo's website optimization and for other search engine is not much different, the difference is only reflected in the details (note: For the current Yahoo! and Yahoo Chinese relationship, we are not clear, but according to general understanding, Yahoo Chinese does not seem to have its own dedicated algorithm, Ranking algorithm should be basically the same as English Yahoo, but added some Chinese characteristics of the amendment, such as 3721, as for 3721 is not the impact of SERP and how the impact of SERP is unknown. Let's say the algorithms used are the same. )
Optimization of HTML code
Yahoo! is more interested in HTML code than Google and MSN. Many tests have shown that errors in HTML files may have little or no effect on Google or MSN, and do not prevent the page from appearing on the front of the SERP, but are much less likely to succeed in Yahoo!. Similarly, a Web site or Web page that has fixed HTML errors and is completely authenticated by the Yahoo! is almost impossible to detect in Google or MSN, but it can be found in a qualitative leap in the rankings.
In web design and production, for Yahoo! Optimization mainly includes, 1, Yahoo! that appear in the HTML file before (and the page appears at the top of the above is not the same concept) content is important content, which requires us to put the important part of the page prominently HTML file head; 2, Good design of the Web page has a lot of refined code, such as the use of external CSS files, JavaScript files, and so greatly reduce the volume of HTML, such as less or no table can also improve the efficiency of the HTML code, these can be to a large extent to highlight the real content part of the page. In fact, the above two are also not to be ignored for other search engine optimization, but Yahoo! give it a higher weight.
Keyword density
Because the search engine algorithm is always in the adjustment, therefore, the specific keyword density is certainly not realistic, and, keyword density is not a universal number, in many cases with the industry different types of Web sites, the best keyword density is also different. Therefore, the feasible approach is to analyze the site corresponding keywords SERP, analysis of the top 10 sites or Web pages used by the keyword density, after all, the ideal keyword density is always regular. Typically, the top 10 sites in Yahoo Serp, according to the competitive keywords, keyword density in addition to very individual 0.5 to 1% (low-end) and 5.0 to 8% (high-end), most of the between the two, At this time as far as possible the keyword density set to slightly below the maximum value generally can achieve optimization purposes.
Reverse Link
On the reverse link, in the big aspect of the rules of the search engine is not too much, in the content-related sites using keywords as anchor text of the inverse link is also the Yahoo ranking algorithm is a crucial factor. In contrast, Yahoo! to reverse-link processing is more similar to Google, and MSN is slightly different.
In the site optimization for Yahoo!, reverse link must be considered:
Quality of links
Similar to the way Google uses PageRank and TrustRank to determine the quality of the inverse link, Yahoo! uses similar techniques to eliminate unrelated links or spam, and in the Yahoo! Ranking algorithm, the quality of the link is heavier than the sheer number.
In Google's site optimization, the quality of the judgment link can often be weighed by viewing the PageRank of the link source site, although the PageRank shown in Google Toolbar is not accurate, but at least a relatively simple basis for judgment. So how do you determine if a link is judged by Yahoo as a high quality link? The simple way is to see if the linked source site appears in the Yahoo! the same or similar keyword SERP position, if you want more accurate judgment, also need to view the site's whois information, Yahoo! generally think can rely on the site of the domain registration time of at least three years, Also depends on whether the source site has a sufficient number of non-exchange links, as well as the number of outbound links from the source page, the number of outbound links on the same page, the smaller the impact, and so on.
Location of links
In the same way, it is important to note where the link is in the page. Simply put, links that appear on the front end of the HTML are more efficient than those that appear later, and links that use special formatting, such as bold, italic, and other colors or fonts that are different from the page, are more efficient.
Linked anchor text
We have discussed the anchor text of the link more than once, as in the case of Yahoo!, no longer repeating it.
One-way link
Two-way exchange links are not completely ineffective in Yahoo!, but their impact on rankings is far less than one-way, content-related links, because in many cases such links are closer to the evaluation of content excellence.
The impact of time on a website or web page
Similar to Google's sandbox, Yahoo! also uses a similar "Aging" mechanism: New Web sites run at least 6 months or longer, making it difficult to get a good ranking, even when optimized technology is applied perfectly; The new link will not soon play its role in the promotion of rankings, often need 3-4 months of its effect will gradually reflect. However, compared with Google, the Yahoo! of the "test" mechanism, the intensity of slightly smaller. But this combination of new sites and new links often leads to a lot of new sites (links to new sites that are definitely new), and it's hard to get a good ranking for competitive keywords within a 8-month to 1-year timeframe.
